What is going on with Alton Towers? For years, they have have had basically only a First bus to Stoke and the X52 but in the past year, they have gained 3 buses.
Good luck to High Peak, others seem to have made a success with their Towers buses so hopefully this will be another one to add as a regular service. Only thing which could work against them is it being Sunday only.
For many years I have been bemused by the lack of a decent service to Alton Towers. It is (or was) the second largest paying tourist attraction in the country (or some such claim) and yet it merited just one advertised bus each way per day - the First 32 service you mention (previously Potteries Motor Traction / PMT X39). This operated as a rail connection from Stoke Station with through fares available and was timed for the London train. There was a very limited local service (239) which passed the entrance.
It was also a very difficult route to run. Physically it required specially geared double deckers for the hill between Oakamoor and Cotton. Secondly on a rainy day it could carry only a handful of passengers yet on a sunny day it could fill five double deckers. 30 or so years ago such things were much easier to resource with larger fleets, a larger pool of drivers and spares sat on the bus park (and drivers in the canteen) that the inspector (remember them!) could call upon. The money it could take on a busy day - with inclusive Towers admission paid to the bus driver - was substantial.
Then First dropped the ball, or perhaps like many of its longer distance services, it retrenched as they preferred to concentrate on their 'Overground' network. Having buses two hours away from the home area, with a mechanically unreliable fleet, causes headaches!
The PMT service, and the D & G service (32X) when first introduced operated on the back of the Alton Towers staff service (generally unpublicised to the general public). Between the two Alton Towers themselves operated a public and staff service.
The X52 (Trent Barton, Nottingham to Alton Towers) is a relatively recent introduction.
The X41 (D & G, Stafford to Alton Towers) is a bit more recent than that, and is/was linked to a staff service.
The X70/1 (Hulleys, Sheffield to Alton Towers) commenced last year.
The X99 (Manchester Airport to Alton Towers) is new this year.
The last two make sense as they service populous areas, including large student populations, who may not have access to a car.
One change is the development of hotel accommodation at Alton Towers and their offering packages beyond a simple 'thrills' day out.
